Permanent magnet apparatus for magnetizing multipole magnets

Abstract

An apparatus for magnetizing one or more elements having a predetermined outer surface shape, the apparatus comprises one or more permanent magnets having a cavity therethrough which cavity includes a shape conforming substantially to the shape of the outer surface of the one or more elements. The magnets also create a magnetic field that passes into the cavity. The one or more elements are disposed on a support operator for magnetization so that the one or more elements are magnetized when inserted into the cavity.

What is claimed is: 
     
       1. An apparatus for magnetizing one or more elements having a predetermined outer surface shape, the apparatus comprising: (a) a plurality of permanent magnets arranged side by side in a cylindrical shell having a cavity therethrough which cavity includes a shape conforming to the shape of the outer surface of the one or more elements, and said permanent magnets create a magnetic field that passes into the cavity; and,   (b) a support operator to which the one or more elements are disposed for magnetization so that the one or more elements are magnetized when inserted into the cavity.   
     
     
       2. The apparatus as in claim 1 further comprising a bearing assemblage that forms the cavity, and said permanent magnets are disposed on said bearing assemblage surrounding the cavity. 
     
     
       3. The apparatus as in claim 2 further comprising a structural support positioned for enclosing said permanent magnets. 
     
     
       4. The apparatus as in claim 2 further comprising a bolt, and wherein said operator includes a threaded end for receiving said bolt which assists in maintaining the positional relationship of the one or more elements. 
     
     
       5. A method of magnetizing a plurality of elements having a predetermined outer surface shape, the method comprising the steps of: (a) providing a plurality of permanent magnets arranged side by side in a cylindrical shell having a cavity therethrough which cavity includes a shape conforming to the shape of the outer surface of the elements, and the permanent magnets create a magnetic field that passes into the cavity; and,   (b) inserting a support operator, to which operator the plurality of elements are disposed, into the cavity for magnetizing the elements.   
     
     
       6. The method as in claim 5 further comprising the step of providing a bearing assemblage that forms the cavity, and the permanent magnets are disposed on the bearing assemblage surrounding the cavity. 
     
     
       7. The method as in claim 6 further comprising the step of providing a structural support positioned for enclosing said permanent magnets. 
     
     
       8. The method as in claim 6 further comprising the step of providing a bolt, and wherein the operator includes a threaded end for receiving the bolt which assists in maintaining the positional relationship of the plurality of elements.
